Frig is 10+ years old but has begun frosting up the evaporative coil, blocking airflow. A manual defrost has the frig/freezer working well again... for a while. I suspect it is the defrost module and bought a new one.

I popped the plastic cover down from the top of the frig but do not see the module.

There are (3) 1/4" hex head screws holding the assy up; two near the front door pointing upward and one to the right of the water filter pointing to the rear. Then there are (2) Phillips head screws behind the light bulbs. After removing those (5) screws, the entire top assembly drops down and the Adaptive Frost Module is easily popped out from the top.

I looked at my old board and the 22uF/50V capacitor is clearly blown. I'll replace that and use it as a spare. Radio Shack doesn't carry this exact cap so I'll pick it up on the Bay.

I just picked up (25) 22uFx50V on the Bay for $4.90 including shipping.

Is the failure humidity related or only the result of the spikes? If it is 'spikes' then it's doomed to fail again. Otherwise I could dip the board in the rubber handle goop, or at a minimum, epoxy the cap using an old paint brush.
